Title: Manufacture of mesa-type semiconductor substrate
Inventor: YOHANESU YORUDANUSU MARIA BINS
IPC: G02B6/13
Filed: 1990-09-12
Abstract: PURPOSE: To cause at most slight under-etching, by allowing an etchant to be non-selective for a semiconductor material oxide and selective for a semiconductor material. CONSTITUTION: For layers of a semiconductor layer 3 forming a quantum well, three layers of semiconductor layer 3' for forming a barrier, and a region 12 comprising an SC layer 2' and an SC layer 4' are converted into a semiconductor material oxide by anode oxidation. The part converted into the semiconductor material oxide is removed by etchant which is non-selective for a semiconductor material oxide and selective for a semiconductor material. Thus, both removal of an anode oxide and an oxide is performed non-selectively. Thus, under- etching does not substantially occur at any one layer of the semiconductor layers 2', 3, 3' and 4.

Title: Electrochromic display device
Inventor: MIZUSAKI YASUSHI
IPC: G02F1/1516
Filed: 1988-09-29
Abstract: PURPOSE:To prevent the deterioration of the device by using a metal phthalocyanine deriv. for an electrochromic material on a display electrode side and using the metal phthalocyanine deriv. which is previously maintained in a reduced state to a counter electrode. CONSTITUTION:A display plate is formed by laminating transparent electrodes 2 and the electrochromic (EC) material 4 on a substrate 1 to form a display plate. The part of the electrodes 2 where the EC 4 is not laminated is masked by a film 3 consisting of an insulating material. On the other hand, the counter electrode is constituted of the transparent electrode 7 on a counter electrode substrate 8 and a counter electrode member 9. The metal phthalocyanine deriv. is used as the EC material 4 and the metal phthalocyanine deriv. which is previously maintained in the reduced state is used as the counter member 9. The metal phthalocyanine of the display electrode side restores the further stable neutral state o brown to blue and has no possibility of deterioration even if a color change is caused in the blue to brown reduction region by applying a negative charge to the metal phthalocyanine on the display electrode side. The deterioration of the counter electrode is, therefore, suppressed and the long life is obtd. even in case of driving the display device by impressing a negative voltage thereto.

Abstract: PROBLEM TO BE SOLVED: To measure the errors with high precision wherein, when the thickness of the second thin film pattern does not exceed a specific value, an optical system for phase difference is used to measure the central positions, so that the super position error may be processed according to the central positions of the respectively processed first and second thin film patterns. SOLUTION: When the film thickness of an etching pattern 32L does not exceed 0.1μm while the film thickness of a resist pattern is about 1μm, an optical system for phase difference is used so as to process the central position XECLS in the X axis direction between aperture stepped parts of the etching pattern 32L as well as the central position in the Y axis direction. At this time, the optical system for bright field is used so as to process the central position XRC in the X axis direction between the stepped parts of the resist pattern 31 as well as the central position in Y axis direction. Through these procedures, the former difference between the processed central position XRC and the central position XECL is assumed to be the superposition error ΔXE while the difference between respective central positions in the Y axis directions of the resist pattern 31, and the etching pattern 32L is assumed to be the superposition error ΔYRE.

Title: Emitter follower circuit
Inventor: KANETANI KAZUO
IPC: H03F3/50
Filed: 1992-09-11
Abstract: PURPOSE:To reduce the power consumption of the emitter follower circuit. CONSTITUTION:A drain of a MOS transistor MP of a (p) channel, a base of a pull-down transistor Q2, and one end of a discharge circuit CSW are connected, and on the other hand, a source of the pMOS MP and a collector of the pull-down transistor Q2 are connected to an emitter of an emitter follower transistor Q1. In such a state, a base of the emitter follower transistor Q1 and a gate of the pMOS MP are driven by a signal of the same phase. In such a way, at a transient time when an output OUT is switched from H to L, a large current flows to the pull-down transistor Q2, and at a transient time when its output is switched from L to H, a large current flows to the emitter follower transistor Q1. However, at a steady time of H and L, only a small current flows in both of them. Therefore, the low power consumption is attained.

Title: Manufacture of short-arc discharge lamp
Inventor: BAN YASUO
IPC: H01J9/32
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To prevent variation of arc length and the movement of electrodes to achieve shortening of an arc, long life, and enhancement of operability by driving independently a first mold sealing the contour of an electrode core rod at each end of a light emitting tube made of quartz and a second mold sealing the contour of sealing foil, and reducing the force to press the first mold which is the first to be pressed during melting. SOLUTION: Foil of molybdenum or the like, buried in a sealing part at each end of a light emitting tube and connected to an external lead wire, has one end connected to an electrode core rod. When the end is fabricated by a mechanical punch sealing method, a first mold 21 which comes into contact with quartz melted by heating and which thus seals the contour of the electrode core rod is almost uniformly and weakly pressed by the buffer action of a pushing spring 23 or the like which is mounted on the opposite side to the surface making contact with the quartz. Since the force to press a second mold 2 sealing the contour of the foil during the next process is large, the unmolten quartz can be treated immediately. Therefore, electrode positions are secured, forced elongation of the foil is avoided, and complete sealing is made possible.

Abstract: PURPOSE:To realize perfectly remove the resist film without elongating remarkably the ashing time by applying ozone generated by short-wave ultraviolet to a processing object and then applying plasma thereto under the oxygen ambience. CONSTITUTION:The processing objects S are arranged in parallel on a boat 5 and are put into a processing chamber 1. Oxygen is then supplied to the processing chamber 1 and ozone generated is applied to the resist film by irradiating the entire part of resist with the shortwave ultraviolet from a generating tube 6. Thereby, the resist film at the surface of processing object used for ion implantation and dry etching can be ashed. Next, a high frequency coil 4 is operated in such oxygen ambience in order to generate oxygen plasma. Thereby, the resist film is ashed after elimination of alternating layer. According to the above method, the resist film is certainly gasified in each process,resulting in no residue of resist film and deposited film used for the mask of ion implantation. Therefore, necessity of processings in the succeeding wet processes can be eliminated.
